ALBERT HOILAND, OF NOME, NORTH DAKOTA.

, WILD-OATS SEPARATOR.

To all whom, it may cancer-n Be it known that l, ALunn'r HOILAM), a citizen of the United States, and a resident of Nome, in the county of Barnes and State of North Dakota, have made certain new and useful Improvements in Wild-Oats Separators, of which the following is a specification.

My invention relates to improvements in devices for separating wild oats, quack from cultivated oats, wheat, flax, barley, and other grains and it consists in the combinations, constructions and arrangements herein described and claimed.

An objectof my invention is to provide a simple device having a few parts, and con sequently not liable to get out of order, which will quickly and effectively separate the wild oats from the cultivated oats, delivering the former at one end of the device, and the latter at the other end.

A. further object of my invention is to provide a device which can be operated by hand or by power devices.

Other objects and advantages will appear,

in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention illustrated in the accompanying drawing forming part of this application in which Figure l is a longitudinal section through the device, Fig. 2 is a perspective view of the main hopper, Fig.- 3 is a section along the line 3-3 of 1, and Fig. 4 is a perspective view showing the scraping device and the discharge trough orchute.

in carrying out my invention I provide a frame, which consists preferably. of end members l and 2 respectively, joined together by longitudinal braces 3 and transverrzc braces 41. The frame is preferably made of pipe, bent into the form shown in the drawings but may be made of any suit able material and of any suitable shape without departing in the least from the sp rit and the scope of the invention.

Disposed at the upper ends of the end members 1 and 2 are bearings 1 and 2 r spectively for a shaft cline-t as shown in the drawing. This shaft Specification of Letters ratent.

ing preferably made .of sheet metal, al-

though it may be made of other material such as wood or the hire. 'lhe drum is provided at its ends with flanges or beads 9 extending outwardly. These beads are arranged to he engaged by idler-s 10., One of these idlers is carried by an arm 11, which is secured to the frame by means of a pin 12, which passes through the frame and is provided with a nut 13. The position of the idler 10 may be shifted by unloosei'iing the nut, moving the arnrand retightening the nut. At the opposite end of the drum, the arm 14-, which bears the idler 10, is also secured tothe frame l. As shown in Fig, 4 the arms 11 and 14 have angular extensions 11- and l f these extensions being connected by a rod 15. The rod 15 forms a support for one end ofa trough 16, which is inclined downwardly, the opposite end of the trough being supported by means of a curved arm 17 secured to a vertical rod 18. The lower end of the rod 18 is secured to the cross member 4. Fig. while the upper end is secured to the top of the frame l, by means of a pin 19, which passes through the arm 14. A nut 20 is provided for regulating the position of the arm it in the manner already described in connection with the arm ll. The rod 15 idextcnded and is arranged to support a rectangular frame of wire or other suitable n'ialerial having side members 21 and 22 respectively. The side member 2i constitutes a support. for a shield or curtain 21, while the side member 22 supports a (lOWllWtll'fllV extending shield or curtain 21*. The trough 16 has proj cting from it a laterally extending chute ill. This hute, it will be noticed, is toward the upper end of the trough or chute. 1(3. lhc arms which support the wire frame also carry two or more wires, which constitute scraping devices as explained later.

A. main hopper 2-1 is provided having a slidable door 25 for regulating the feed of thematerial. This hopper is provided with a spent 26 to which is attached guard plates 27. The hopper is secured to the upwardly extending member 18 at 28. .An integral arm 18 extends laterally from the member 18. A U-shaped bolt 29 secures both the arm 18 and the hopper to the frame 1. The inner side of the drum 9 is provided with a cotton flannel lining 30. A belt 31 passes around the drum and over the pulley 7, while a similar belt 32 .passes around the other end of the drum and over the pulley 8. A guide pulley 9 is mounted on the frame 2, and is arranged to engage the edge of the drum 9 for guiding the latter.

v From the foregoing description of the various parts of the device the operation thereof may be readily understood. The cats containing the quack grass wild oats, etc., is fed into the hopper 521 and passes by the spout 26 into the upper end of the inclined drum. The latter is rotated by means ot the handle 6, or by any other suitable means, and the drum 9, which is suspended by the belts 81 and 32, is also rotated by these belts, the drum being guided in its rotation by means of the idlers 10. The cultivated cats will pass through the drum, and will be discharged at the lower end of the latter, but the beards of the sprouting end of the wild oats will cling to the cotton flannel and will cause the wild cats to be carried upwardly above the chute 16 into contact with the scrapers 23. This will scrape the wild oats oil, and they will fall into the chute 16, which is of suflicient inclination to cause them to be delivered at the lower end thereof. In case any of the wild oats should fall from the flannel before reaching the scrapers 23 they will be guided by the inclined chute 16 and will be delivered toward the upper end of the drum where they will again be carried up by the beard which clings to the flannel. The de vice is rotated in the direction shown by. the arrow in Fig. 3. There is a tendency for the cats to fall over the side of the chute l6, and in order to prevent this I arrange the shield or guards 21 and 21 against which the Wild bats may hit, thereby deflecting them into the trough 16. The provision of the guards 27 prevents the cats from passing out of the upper end of the drum.

The arrangement of the idlers 10 and the scrapers 23 I deem an important part of my invention, for it will be apparent that no matter what the movement of the drum is the scrapers 23 will follow it, so as to be always in close contact with the flanneh The adjustment of the arms 11 and 14 also insures the proper working of the device.

In using the separator as described herein, I find that the wild oats are completely separated from thescnltivatcd oats. None of the cultivated oats'will cling to the flannel, but

messes will be delivered from the lower end out the drum, while all-of the wild cats will eveutually be delivered into the chute 1.6. Ti is therefore no necessity of running the cats more than once through the device.

My device is exceedingly simple in nature,- it has few parts, and is therefore liable to easily get out of order, and accomplishes as perfect separation as de vices of a far more complex and a nat-ure.

I claim:

1. In a wild oats separator, a rotatable incliued drum open at both ends, means on the interior of the drum tor engaging projecting portions of certain of the grains tor clevating the latter, a frame, a scraping device carried by said frame and arranged to can,

tend through the drum, an inclined delivery chute disposedbeneath said scraping device, and a shield suspended by said frame on each side of said chute.
